GREGORY KOVALAVICI-I, OF NEW YORK, N. Y.

MOTION-CONVERTER.

eeann.

To all whom it may concern:

Be it known that l, GREGORY KOVALAViCi-I, a subject of the Emperor of Russia, and a resident of the borough of Manhattan, in the city of New York, county of New York, and State of New York, have invented new and useful Improvements in Motion-Converters, of which the following is a specification.

My invention relates to motion converters and pertains more particularly to means for converting the reciprocating motion of the piston rod of a marine engine into rotary motion for driving the propeller.

The object of my invention is to produce compact and G'ffiCiGllt means for converting the reciprocating motion of the piston rod of a marine engine which may be horizontally disposed in the vessel.

Another object thereof is to produce a device of said character which may be coupled with a plurality of engine cylinders and piston rods in operation, and a still further object of my invention is to produce a more simple, cheap and e'flicient motion converter than has heretofore been attained.

To these ends my invention includes the combination and arrangement of component parts to be hereinafter described and more particularly pointed out in the claim.

In the accompanying drawings in which like reference characters indicate similar part-s, Figure 1 is a top plan view of my invention, Fig. 9. is a longitudinal sectional view taken on the line 22 of Fig. 1, and Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 1.

Referring now to the drawings, 1 and 2 and 1 and 2 indicate longitudinal bars or tracks arranged in pairs, each pair of which is secured to the cylinder 3 of an engine. Slidably carried between each pair of said bars is mounted the rectangular frame 4:, comprising the bifurcated members 5 which loosely embrace the bars and the cross pieces 6 and 7 connecting said members near their ends.

The cross piece 6 is rigidly attached to the piston rod 8 of the engine, while to the cross piece 7 at the opposite end of the Specification of Letters Patent.

Serial No. 796,918.

frame 4 is pivotally attached the pitman 9. Said pitman is pivotally connected at its opposite end to the crank shaft 10 journaled transversely in the bars 1, 2, 1 and 2 intermediate the ends of the frame l. Said crank shaft may extend through and be coupled with a plurality of tracks and reciprocating frames, the piston and crank in the shaft being alternately arranged.

It will be apparent from the foregoing description and by reference to the accompanying drawing, that the reciprocation of the piston rod reciprocates the frame 4. on its tracks, which through the pitman 9 converts such motion into rotary motion in the crank shaft 10 without appreciable loss of power, and by means which occupies a very small amount of space and which is located on a horizontal plane, all of which are desirable conditions particularly in the construction and arrangement of marine engines.

Having thus described my invention, what I claim as new and desire to be secured by Letters Patent, is

In a device for converting reciprocating motion into rotary motion, a frame composed of channel irons, one of the wings thereof being longer than the other and arranged to extend outwardly, a cross head having ears adapted to rest above and below the channel irons a distance equal to the width of the short wings thereof, arms extending from the cross head in line with the channel irons, and an auxiliary cross head connected to the arms, consisting of two members, each having ears adapted to rest above and below one of the channel irons a distance equal to the width of the short wing thereof, and a shaft connecting the two members of the auxiliary cross head, a link mounted at one end on the shaft connection between the auxiliary cross head members, and at its other end to a crank shaft, said crank shaft being mounted to rotate in the frame between the cross heads.
